Appiicaaon men-Au ust 10, 1905. Serial No. 273,608.

To' all whom it may concern:

. Be it known that I, GEORGE O. BLIOKENS- DERFER, a citizen of theUnited States, re-

siding at Stamford, countyof Fair-field, and

State of Connecticut, have invented certain new and useful 1m rovementsin Tabulator Mechanisms, iullyescribedand represented in the followingspecification-and the accompanying drawings, forming a part of the same.

"I his invention relates to certain improve-- ments incarriage-controlling mechanism for typewriting machines.

It is one of the objects of the invention to provide improved mechanismfor controlling the position of typewriter carriages, this mechanismbeing generally known as a tabulating mechanism, that is, a mechanism bwhich the operator is enabled to write co umns of figures, the carriagebeing automatlcally positioned seats to bring the figures of successivenumbers in the same column in vertical rows. i A further obj ectof theinvention is to producean improved mechanism by which columns of othermatter, such, for instance, as names, can be written, the carriage beingautomatically positioned-so'that the first let.- ter of successive namesin the column will be in the-same vertical row.

With these and other objects in view, the invention consists in certainconstructions and in certain parts, improvements and combinations suchas will be hereinafter fully described and then specifically pointed outin the claims hereunto appended.

Referring to the drawings-Figure -1-isan elevation in perspectiveillustrating so much of the operating mechanism of a typewriting machineas is necessary to an understanding of the-invention. Fig. 2 is a sideelevation of'the machine on the tabulatormechanism side. Fig. 3 is asectional detail plan view,

- the position of the observer-being indicated -'by the arrow 3 in Fig.2, the figure also including asample of workwhich maybe done by themechanism. Fig) 4 is a view similar to- Fig. 3, illustrating amodification. Fig. 5, is a sideelevation of the machine on the powerside. i Fig. 6 is a rear elevation illustrating the operation of thecolumn stop mechanism. Figs. 7.and 8 are enlarged de tail views.

The machine selected to illustrate the in vention is a machine of thewell-known Bliekensderfer type. It isto be understood,

to machines of this particular type.

Referring to the drawings, 1 lndicates a table of the machine, thistable being supable' mechanism, as, for instance, the mechanism shown inthe patent to Blickensderfer,

No. 717,732, dated January 6, 1903. The details of the mechanism bywhich the-printing is effected are not illustrated, for the reason thatthey will not'assist in understanding the invention. The printing wheelcooperates with a platen roll 5 mounted on a shaft 6, this shaft beingsupported in suitable standards 7 rising from a bed 8 connected to sidebars 9 which form a part of the carriage. The carriage is supported bypairs of grooved -wheels 10,- these wheels being supported on verticalshafts rising from the bed 1. \Zhile ient form of carriage mechanism,any other suitable form of carriage mechanism may be adopted. v

'While the mechanism for mowing the carriage may be of any suitabletyne, in the best power mechanism by which the movement of the carriageis effected. The power mechanismniay be varied widely as to its detailsof construction. An efiicient form of power mechanism is that shown inthe patent to Blickensderfer, No. 717,732 above referred to, the sameembodying a constantly running electric motor, thepower shaft of'whiohis indicated at 11 in Figs. 2-, 5 and 6. In the best constructions,furthermore, mechanism will be-provided with means for giving thecarriage a step bystep movement, and also with means for giving thecarriage what may be termed a running movement in contradis- .tinctionto a step by step movement. The means by-which the carriage is given therunning movement are or may be generally similar to theconstructionillustrated in the carriageis provided with a rack 12 which is mountedon a vertical shaft 14', the lower end of this shaft being provided witha bevel gear 15. This gear 15 is in mesh with two gears 16 and1-7arranged on opposite sides .of its center, as in the patent referred to.The gear 16- is fixed to a friction wheel 18 constructions the machinewill embody a in mesh with a gear 13, this gear being however, that theinvention is not confined ported on standards 2 rising from the bed'plate 3. In-the particular machine illustrated, thepr'intin'g isefiected by means of a wheel 4 wh1ch'may be operated by anysuit theconstruction just described is a convenpatent above referred to. Asshown, the

' as the'machine is shown in Fig. 1.

and the gear 17. is fixed to a friction wheel 19, these wheels'beingmounted on-a shaft, not shown, but being well-shown in the patentreferred to. The position of the shaft is indicated by a screw 20 inFig. 5 which holds the wheel 18 on the shaft. As in the patent referredto, this shaft on which the friction wheels are mounted, is mounted in aswinging block 21. The power shaft is provided with two friction wheels22 and 23, the wheel 22 beingopposite the wheel 18 and the wheel 23being opposite the wheel 19. It ,is apparent that when the block isswung so as to bring the wheels 18 and 22 in engagement, the shaft 14will be turned in one direction and will drive the carriage and when theblock is swung so that the wheels 19 and 22 are in engagement, the shaft14 will be turned in the opposite direction and drive the carriage intheopposite direction. In the par ticular construction shown, the blockhas.

secured to it a T-shaped arm 24 (see dotted lines in Fig. 1) this armhaving two projections 25, 26. -The project-ion 25 has connected wit arod 27, the end of this rod bearing adjusting nuts 28 and a sleeve 29having a broad collar 30 thereon. The rod and' sleeve pass through theoutwardly turned end 31 of a bell-crank lever 32 33, this lever beingloosely mounted on a shaft 34 which will be hereinafter referred to.This lever 32-33 bears a key marked Left The projection 26 has a rod 35connected to it, this rod having similar adjusting screws and passingthrough the outwardly turned end 36 of a bell-crank lever 37, this leverbearing a key marked Right. By pressing the key marked Left the blockwill be swung so as to bring the wheels 19 and'23 into engagement andthe motorshaft running, the ca riag' will be driven to the left,

By pressing the key marked Right, the wheels 18 and 22 will' be broughtinto contact and the carriage will be driven to the right, as themachine is shown in Fig. 1. The key marked Left will give the carriage.a running movement in the same direction as the step by step carriagefeed ordinarily employed in typewriting machines, and the key markedRight will return the carriage, after a line has been printed. Thedetails wherein this mechanism for driving the carriage differsfrom'whatis shown in i the patent referred to are not claimed herein,

as thcy are claimed in an application filed by me December 6, 1902,Serial No. 134,104. Vfhile these means have been foundin practice to beeffective for ivin the carria e the b o c:

running movement, it is to be understood that any other suitable meansmay be employed for this purpose.

The step by step feeding mechanism, when such a mechanism is employed inconnection with the running movement mechanism, will,

' of the cam 44.

in the best machines be independent of the mechanism for giving thecarriage the running movement, and, furthermore, in the best machines,will be of such a character as to be disengaged from the carriage so asto leave the carriage free to move at all times. While the constructionof the step by step feeding mechanism may be varied widel T as to itsdetails, in the particular construction shown, there is provided aswinging lever 38, this lever having an angular toothed end 39 which maybe caused to engage with the rack 1.2 before referred to. Thls lever ispivoted on a screw 40 mounted in a block 41 which may be iven a rotatingmovement.v This block 41 as a spring arm 42 connected to it,

a shaft 45 which is driven by a gear 46 from the power shaft 11. Thelever 38 bears on the end opposite its toothed end a cam roll 47 whichruns on a cam formed on the rear side the cam 44 rocks the block 11 soas to bring the angular toothed end of the lever into engagement withthe rack, after which the cam on the rear side of the cam 44 rocks thelever In the operation of this feed,

38 to advance the carriage. This particular feed mechanism is notclaimed in this application, as the same is fully described and claimedin a pending application filed by me Nov. 16, 1903 and serially numbered181,265. r

The tabulating-mechanism employed maybe varied in its details ofconstruction. In the best constructions, this mechanism will include aplurality of stops 48, two of which are shown in Fig. 1. Inthe bestconstructions, these tabulator stops are mounted in the carriage. In theparticular construction shown, the carnage is provided with a notchedbar 49, the notches corresponding in number and position with the teethon the rack 12. This bar 49 may be conveniently supported on arms 50extending from the standards 7 before referred to. The stops areprovided with depending legs 51 which engage the notches. While theengagement between the legs 51 and notches on the' bar 49 might be deended on to hold the stops in position, in t e best constructions,additional retaining means will be employed for this purpose,- thesemeans being of such a character as to prevent the displacement of thestops vertically. In the particular construction shown, the additionalretaining bail. While the bailmight besecured in positionin any suitablemanner, in the particular construction shown, the downwardly bent endsare bent outward and ass throu h per; forations in s ring pins 54w ichpass t rou h the notched ar 49. The under sides of -t e outwardly bentends 53 will be flattened in a "means embodies'a rod52 having downwardlybent ends 53, this rod and its ends forming a seams of the s rings willhold the bail in position,

but at t e same time will allow the bail to be rocked out of'o'sitions'o' as to permit the stops to be shifted. An additionalspring, as 55, may be employed, if desired, to assist in holding thebail'in position, this being de- -sirable where the carriage used isexcepto effect the stopping of the carriage in the proper position forthe printing-of number's tionally long.

The deyices which cooperate with the stops or similar matter may bevaried in construction. As shown, a series of levers 56 is provided forthis purpose, these levers being loosely mounted on the rock shaft 34.The

upper ends of these levers are bent inwardly, as indicated at 57, and byrocking any one of the leversmay' be positioned so as to engage a stop48. In the best constructions, an additional s'teadying device'will beemployed to prevent the spring of the levers under the impact of thestop as the running carriage strikes them; While this steadying devicemay be varied in the details of construction, as shown, it consists of ablock 58 which may be conveniently mounted on a frame.

bracket 59 extending from the machine This block is secured to thebracket by screws, or inany other suitable manner, and is channeled asindicatedat'60 (Fig. 3), so that the block forms what may be termed acomb, the bent ends 57 of the. levers moving between the teeth of thecomb.

The means for operating the levers when I levers are employed forcooperating with the stops may be varied widely, but in the bestconstructions, these means will be of such a character that theoperation of throwing a lever. into position connects the carriage tothe driving mechanism so that it may be given the running movement. Inthe particular construction shown, a series'of actuating bell crank keyl'evers 61-62 is employed for this.purpose,.these key levers also beinglo ose- 1y mounted on the shaft 34; The connections between'each of thelevers 6162 and the operating lever 56 which it actuates, are, in'theparticular construction shown, formed by means of springs 63, one end ofeach spring being secured under a lip 64 on the part 61 'ofthebell-crank levers. The springs are fulcrumed onthe lips '65 on the parts62 of the levers and are hooked under the lever 56, the ends of thesprings being caught in one of two notchesindicated at 66 in Fig. 1.

It will be seen that by pressing any particular one ofthe levers 6162,the corresponding lever '56 will be thrown up into position so that itsend 57' will cooperate with a stop 48. The arms 61 bear keys which mayhave conventional indications to indicate the numbers to be printed. I

The means b which the position of one mech anism into operation may bewidely varied. As shown, the shaft 34 forms a rock shaft and is utilizedfor this purpose. This which underlies the part 61 of'all the levers61-62, so that the depression of any lever rocksthe shaft 34. The shaft34 (see Figs. 7 and 8) has an arm 68 extending therefrom at the endopposite the end which has the arm 67. portion 69 through which the rod27 before referred to passes. This arm bears against the end of thesleeve 29 before referred to. When the shaft 34 is rocked, the outwardlybent end 69 of the arm 68 strikes the end of the sleeve-29 and moves therod 27, this movement rocking the block 21 and bringing the frictionwheels 19. and 23 into engagement so as to advance the carriage to theleft. It'will be seen that this movement will be effected withoutdisturbing the connec sleeve 29 moving through the opening in theoutwardly bent end 31 of the lever 32. A. depression of one of the keysof the leversvers 56 into position to cooperate with the stop 48 andwill, at the same time, cause the carriage to be moved until the stop 48strikes the lever, at which time the carriage is in position to rint thenumber.

The tabu ator mechanism, in the particutabulating of figuresrepresentingdollars'and (cents. "In operating the mechanism, the stop 48is properly positioned on the notched member 49, a convenient way ofpositioning decimal point in the column at the pro er place on thesheet. Then, if it be desire to print the number 67 25-, as it appearsin Fig. 3, for instance, the ten key appearing at the left in Fig. 1will be depressed. This will up into position to strike the stop 48 andat the same time will rock the shaft 34 and esshaft and the shaft 14, sothat the carriage will be given a running movement until the stop- 48strikes the end 57 of the lever 56. The carriage is now properlypositioned for printing the number, and the 6 key, (not shown), on thetypewriter. is struck. After the key 7 on the typewriter has beenstruck, (this key not being shown) the spacebar is 7 and the 2 reresenting a decimal point, or a period might e struck, if desired.desired to print a higher number, as, for instance, the number 71092 03,as it ap ears in Fig. 3, the middle one of-the "ten eys, 1 as they(appear in Fig. 1, will be struck, the pa errol'l beingturned if it isdesired'to print this under the revious number. The

This arm 67 'has'an outwardly bent tions before described fromthe lever33, the

struck in'ord'er to make a space between the shaft has extending from ita broad arm 67 6162 will, therefore, throw one of the lelar machineillustrated, is arranged for the I it being to place it at a point tobring the" throw'the end 57 of the corresponding lever tablish theconnection between the power j Ifitbe of the levers. t ows the carriagemoving striking'of this dle-fften key will posi 3o tion the carriageproperly so as to bring the figures in proper relative position withrespect to the key previously struck, the runglllg movement of thecarriage occurring as e ore.

It will be seen that the guiding or steadymg comb in its operationsupports the end of the leveriagainst the impact of the stop on thecarriage and thus enables comparatively light levers to be used and thetabulator to be gotten into a small space. This steadying comb may alsobe availed of to space the numbers if desired. When it is desired thatthis be done, the tabulator keys may be arranged as in Fig. '4. In thiscase a space is left between the key representing hundred thousands andthe key representing millions, and a similar space is left between thekey representing hundreds and the key,

representing. thousands. With the keys spaced in this manner, theoperator in printmg; the first number appearing in Fig. 4, will strikethe spacing key between the figures "3 and 4. In printing the secondnumber, however, of the column, the 1 will be brought by the hundred keyinto its proper position beneath the 4 of the first number.

Where a plurality of columns is to be printed across a sheet, it may bedesired not to print a number on a given line in the first column orcolumns, but to begin the printing with the numbers in the second columnor a the machine.

subsequent column on thesame line, and to do this without 0 erating thespace bar of W ile the machine may be constructed in various ways toaccomplish this result, in the particular construction shown the spacein thecomb which the cts lever occupies is made wider than the otherspaces so as to ermit a sidewise movement of this lever. n the bestconstructions, a

spring marked 70 is' interposed between this lever and the side of thecomb space. By

depressing the cts lever, the machine will be operated as beforedescribed, and the stop 48 for the first column, for instance, if this-.be the column where-it is desired not to print, will be brought intocontactwith the cts lever, and will push the lever over against thetension of the spring 70. The lever is now released and as it isreleased is pushed backby the spring 7 0. By striking the roperdenomination key the carriage will e advanced in the manner before de--scribed, so as to bring the carriage into proper positi u to print theproper number. -.on the Y linelin 1 the second column. mounting the Fctslever in the manner described, it maybe used to jump-the carriage fromcolumn to column as desired.

" It may be desired to associate with the tabulated columns of figuresother printed v matter, such, for instance, as-names ordescriptivematter, and to do this, it is desirpreceding line.

able to have this matter so rinted that the first letters of the columns0 printed matter will be in the same vertical lines. ticular machineillustrated is provided with means for eilecting this result. Whilethese The parmeans may be varied, in the particular c'onstruction shown,the machine is provided with a series of column stops, marked 71,

these column stops being shown as mounted on the same bar 49 asthetabulator stops are mounted on.

hile the construction of this stoppingniember may be varied, asshown, itcomprises a bell-crank lever 7273 pivoted at 7 4 in the frame of themachine. The arm 72 of the bell-crank lever is .provided with a pivotedmember or arm 75 which is normally held in the position illustrated inFig. 6 by means of a light spring 76. The arm 73 of the bellcrank isconnected to a bent link 77 pivotally connected at 78 to a lever 79.This lever 79 is pivoted on the shaft 34 before described,- and itsforward end has a lip 80 extending therefrom which underlies the lever33 before described. The stops 71 are so posi- A stopping. member is.em- .pmloyed which cooperates with these stops 71.

tion'ed that their operative parts are out of line with the operativepartsof the stops 48. When these stops are used, a number of themcorresponding to the number of columns to be printed are placed on thebar 49, and in the particular construction shown are held in osition bythe bail 52 before referred to.-

t has been stated that the depression of the lever 33 connects up thepower mechanism and causes the carriage to be advanced toward the left.It will be seen that the depression of thislever also, through the lip80, rocks the lever 79 which in turn rocks the bent lever 77. This leverswings the bellcrank 727'3 forward, bringing the member 75 into positionto strike the stop 71. I This 'willstop the carriage at the proper pointto "anism is a desirable adjunct to be used in connection with a'tabulating mechanism, it will be readily seen that it maybe used alone,if desired, for printing successive columns of printed. matter.

r The operation of the device will be fully understood. from thepreceding description.
